" Fsck Failed please repair manually and reboot. the root filesystem is currently mounted as read-only. to remount it red-write do :

 

bash# mount -n -o remount,rw /

only CONTROL+D will reboot the system in this maintenance mode shutdown and reboot will not work give root password for login : i entered the password here

# ( here i tried the command mount -n -o remount,rw / )

I got the following error

ext3-fs warning:check time reached, running e2fsck is recommended

ext3 FS on dm-0,internel journal

# JBD: barrier-based sync failed in dm-0 disabling barriers

 

 

Solution :

 

1. Reboot your system and wait for FSCK run.

2. Use following steps to :

 

umount /dev/hddXXX

fsck -CV /dev/hddXXX

 

or

 

fsck -CRV /dev/hddXXX

 

since the fs is mounted read/write
